, 'Application i iled April 7,

My invention relates concrete" construe tion and more particularly to a furring anchor and the method of installing the same for the f' V attachment of a complementa'ryframe-struc- Y ture, interior finish, light, machineryor other devices.

Inthe present invention there is contemplated an anchor device which may be em-,. bedded inthe concrete structureby being at tached to the interioriof the form and around; which the concreteis poured while in fluid 'or} plastic state, thereby insuring firm and secure,

embedment and interlocking engagement with the concretebody. The'preferred form of anchor consists of a U-shaped insert preferably though not necessarily stamped from,

sheet metal, the upstanding arms of which are crimped, corrugated or of otherwise irregular I e outline to atfordinterlocking anchorage Wlt-hin the concrete body, The transverse interconnecting portion of the Ushaped insert ismedially scored or weakened to enable it to be broken or separatedsubsequent,to the embedment of the anchor,'the wings or ears formed by such breakage or separation being. adapted to be flexed outwardly into outstanding angular relation with the concrete body for engagement with the fu-rring strip 01,

, other member to be attached. These attach-e ment ears or extensions, initially intercom nected, are perforated to receivenails from the interior, while in "their interconnected able to secure. In lieu of this construction,

the attachment wings or-ears may beinitially; disconnected but extended one toward theother in a'common plane from theupstanding anchor arms, which may be permanently interconnected by a transversetie as-shown and described .in my co-pend-ing application,

Serial No. 750,159 since matured into Patent The object of the invention is, to, simplify the structure as well as the means and mode same perforations are subsequently employed 1924, s riainbjmeeea' of installing such anchors, whereby they will not I only be cheapened in construction, but will be more eflicient in use, more securely. and firmly embedded,- durable, easilyjapplied'andf ,3

In laying wooden floor upon a concrete foundation, or base, it is desirable to anchor 10 or. otherwisesecure. stringers or furringstrips to such foundation, to which the flooring may be nailed. In the course of concrete building construction, it becomes necessary to' apply furring strips to the side walls and to the v V ceiling for supporting interior finish, attach .2 a sidewall; 'The present anchor is adapted "tobe embedded inthe concrete bodywhile ing interior frame partitions, for supporting a shelvesor cupboards, and for attaching light machineryiand the like, which it may be 7 sirableto suspendl from a c'eilingorsecure to still in plastic state; with its attachment wings illustrated, in its simplest and preferred form in Figs. 1to 4: ofthedrawings, wherein'itconor Qears in. retracted relation, such attachment wings, being extensible subsequent to the re-.

for temporarily. securing it to the form board.

As an inexpensive and rapid means of instal-1 j. lation',- axnumber' of these anchor. members:

. may be -mounted"upon separate form boards 7 :in alignment with each other, preparatory to building the 'for'msfas shown in- When assembled into a concrete form or mold, such anchor' memberslwill extend withinthe mold as shown in Fig. 4, with the trans; verse" connecting portion 2, comprising theattachment wingset abutting the face of 69.;the"form, andthe corrugated or crimped shown inFig. 2. The wing portion 4+4 of the interconnecting transverse portion 2,

then lies in the plane of the surface of the concrete body,whetherit bea .wallor aceiling. In thecase of a concrete floor or foun dation, the anchor members may be thrust intotop-surface of the concrete body while still in a plastic condition. The arms 11 arethrust'into themass until the transverse portion 2 is flush withthe surface of the con crete body. After the concrete has suii'iciently set and hardened, the formboards are. torn away, leaving-the, anchor member embedded in the hardened concrete body withthe'nails 6 from which the form boardshave been de tached protruding from the anchor members.

The strain of removal or detachmentjof the form boards willor'dinarily be suflicie'ntto start or'b'uckle the transverse connecting portion 2 of the anchor. This transverse, portion is then broken by being pried outwardly, the

line of breakage-orseparation being upon the medial score line 3, thus detaching the wings or ears 4-4 one from V the other.

These wings are then bent'outwardly to a po sition substantially at right angles to the face of the concretebody, as shown by dotted lines in Fig. 1, and as shown at b inFigs. 2 and.5.. There is shownat a in "Fig. ,5, th e anchor,

member as disclosed upon the removal of the form board, and before being extended as other structural member 9 is then interposed between the projected or exten dedwings l-A into such stringer or furring strip, through the perforations 5 a direction opposite to that in which the nails 6 were driven for attachment tothe concrete form. Itp'will be noted that the construction enables the furrinsr strip or stringer -9, to bear directly against the face of the concrete body throughout substantially its full length.

The anchor thus enable'sa firm and extended bearingsurface forthestrip9. By fixedly at-.

tachment wings or ears 44 when extended is insured. The anchor members are made in various slzes, and widths to accommodate stringers or furringr strips of different dimen" sions and also to aifordanchors of greateror':

less strength, in accordance withthe condi;v

on's of use, and .thestrain to which they are e to be subjected. The method ofinstallationment of the concrete forms does notitself brealr the wings l l apart and partially flex them outwardly, after whichitis only necessary to bend them to parallel relation byia' hammer blow. 1

In Fig. G is showna modification wherein the extensible'wing portions t e are nor.-.v

mally and initially disconnected, one from the other,-but are extended inwardly in a common plane. The'anchor arms 1 are. interconnected by a transverse permanent connecting tie bar 11,,which formed integral with the wings4 and the anchor arms 1 Like the construction. previously described, this anchor is adapted to be embedded in :the concrete body by being secured to theinterior of the concrete form by. nails being driven through the perforations ofthe wings P.) The concrete mass is poured about the anchor 1, and upon removal of the form boards the wings 4 are flexed outwardly to extended position, as before described. In this construction the anchor arms are permanently interconnected by the transverse tie 11, even after embedment in the concrete body, where as as shown in Fig. 2, after separation of the attachment wings Hithe initially described construction; comprises two independent hangers embedded throughout a portion of their length in the concrete body with the protruding ortions attached to the opposite sides of the furring-strip'or stringer.

For conditions of use wherein the anchorfi is subjected only to minor strains, or for attaching small strips, it may bedesired. to"

employ only one attachment wing or car, in which case the unit may be broken into two L-shaped members before installation,

or such single anchors maybe initially pro duced in L-shaped form as shown in Fig. 7. Such single anchor is installed in the same manner by temporarily nailing the laterally projecting wing portion 4 to the interior of the form, and after removal of the form bending such wing outwardly as indicated by dotted lines in Fig. 7.

From the above description it will be ap-" parent that thereis thus provided a device of the character described possessing the particular features of advantages before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrange-' ment of parts Without departing from'the principle involved lor sacrificing any of its advantages. y
